Another social network that has become very popular in the past few years but is marked by a lack of marketing data is Tumblr. It’s a fertile petri dish for some of the web’s most contagious content and has a fascinatingly wide demographic profile. And with the added buzz it’s getting from the much-talked about Yahoo acquisition, social media professionals should not ignore it.

Gnip gave me access to the Tumblr firehose a little while back and I used it to collect a random sample of more than 300,000 posts. I analyzed that dataset and found several points of interest to marketers.
